TaleBlazer is a new rich Internet application from MIT's STEP lab to author smartphone location-based augmented reality (AR) games. Announced during summer '11 and demo'ed for the first time at CSCL in Hong Kong, it will break new ground in location-based AR game building. Features will include:
Visual blocks-based scripting - prevents syntax errors, while enabling programming of rich interactivity.
Interactive data layers and sampling - create models for player exploration and discovery of thought provoking scientific topics.
Conditional dialog creator - interact with characters in new ways; no more single-track conversations
No local installation - the TaleBlazer Game Maker will be entirely web-based for easier implementation in schools and elsewhere

SCVNGR is a game all about going places, doing challenges and earning points. The game is played from a custom app on iPhone and Android as well as via SMS. It is not a text message scavenger hunt. Instead of riddles to guide you to a place, SCVNGR concentrates on completing challenges at a particular location.
